Dude, don't let the "off road" guys scare you. Youre catted MRT H is not holding much HP. On top of that, the sound is not ANYTHING like your "stock H just a little more flow".
Thats Bull****.
You will feel it noticably faster with that midpipe alone. You might lose 5 HP overall compared to an off road H. Is it worth it, to keep your car a little more tame sounding, deeper, and throatier? Not to mention, you'll be able to breathe at stop lights.
+1,000,000!!!! I love how my MRT catted H sounds with the bassani cb. All my buddies laugh because I dont run an off road H or X. IMO having no cats wasnt worth it, because it was too raspy & crackly for my taste, too loud, & you probably only gain a few extra horses over the catted h.
